As shown in Figure 3a, differentially expressed proteins in the comparison of PP versus CC were enriched in the transforming growth factor (TGF)-β signaling pathway, peroxisome, nuclear factor (NF)-κ B signaling pathway, drug-metabolism enzymes, glutathione metabolism, interleukin (IL)-17 signaling pathway, carbon metabolism, African trypanosomiasis, and malaria, the latter two of which were significantly enriched (p < 0.05). This evidence concerns the gene TGFB1 and human African trypanosomiasis.
